6 Claims.

This invention relates to the manufacture of wood heels.

Difficulty is encountered in the covering of wood heels for shoes inthat the material, particularly in the case of pyroxylin, whichis usedfor covering them, is often cut by the sharp edges of the wood heelblocks, especially at the edge where the attaching face and the rear andside surfaces intersect. The angle between these surfaces, especially atthe rear end of a high Louis heel, is quite acute, and the edge, asformed upon the hard wood by two separate cutting operations, one foreach surface involved, is dangerously sharp and often cuts through theheel cover as the cover is stretched over the heel, or damages it sobadly that the heel becomes spoiled after a little wear.

This difficulty has been dealt with in the past by treating theobjectionable sharp edge on a sand 90 wheel by hand, which is expensiveand produces irregular and inaccurate results.

The object of the present invention is to avoid this difficulty bydulling this sharp edge in an expeditious, accurate and uniform manner.Accordingly I have provided a simple and inexpensive machine having aguiding table with a surface closely adjacent to a rotary rubbing toolwhich is preferably ribbed on its operative surface and convenientlyprojects through a suitable hole in the table. Inasmuch as almost nomaterial is removed from the heel block in the operation contemplated,the heel block may be held in the operators fingers, with its attachingface resting on the table, and slid around in light contact with thetool from one side to the other, with the result that the undesirablesharp edge is suitably dulled.

Advantageously, also, I provide a rotating brush, flush with the surfaceof the table against which any splinters resulting from the operationand hanging to the work piece may be removed in the same manner.

These and other features of the invention comprising certaincombinations and arrangements of parts will be apparent from thefollowing description of a preferred embodiment of the invention shownin the drawings, in which Fig. 1 is a perspective view of the machine;

Fig. 2 is a side elevation; and

Fig. 3 is a detail of the rotary tool.

The illustrated machine comprises a frame ill having two extending armsl2 on each side to hold boxes M for the work pieces. The frame itsupports a flat table It provided with a round hole l8, below which islocated a vertical spindle motor 29. The motor spindle carries a rotarytool 22,

preferably as shown in Fig. 3.

The tool 22 is disk-shaped and has a vertical plain circular edgemerging into a horizontal ribbed shelf 26, which is located just flushwith, or at least not below, the surface of the table [6. A ribbedconical surface 28 rises from the shelf 28, a short distance inside itsedge, forming an obtuse angle 29 between the surfaces 26 and 28. Thetool 22 rotates clockwise as seen in Fig. l.

lhe motor spindle is preferably provided with a pulley, shown as coveredby its driving belt 30 in Fig, 2, which operates a wire brush 32. Thisbrush has its front side lying on the table It and is preferably made ofbrass wire.

The tool 22 is covered by a guard 34% which is formed with two gageplates 36 (Fig. 1) and 33 (Fig. 2) wrapped around the tool 22 and endingat points preferably a little less than 180 apart on the periphery ofthe tool, leaving a. little more than half the periphery exposed.

In operating the machine, the operator places a heel it on the tablewith its attaching face down and its breast toward him, as shown in Fig.1, and slides it over to a position somewhat to the rear of that shownin Fig. 1, with its right edge it against the. gage plate 36. He thenslides it on the table without substantial alteration in itsorientation, keeping the edge G2 in light contact with the conicalsurface 28, in the angle 29, until he has brought the left edge 44 tothe gage plate 38. This operation breaks down the sharp edge' lZ- bl.Such portions of the originaily sharp edge as are bent downward arerubbed away or broken up by the surface 26. In

case any splinters are left clinging to the heel the operator will runthe heel around the brush 32, in the same manner as already described,which will remove them.

Having described by invention, what I claim as new and desire to secureby Letters Patent-of the United States is:

l. A rimming machine for wood heels comprising a flat table, and apercussive tool moving substantially flush with the surface of the tablewhereby a sharp edge of a heel surface resting on said table may bedulled.

2. A rimming machine for wood heels comprising a fiat table having around hole in it, and a ribbed circular rotary tool mounted in saidhole, the ribs extending in a direction which intersects the plane ofthe table.

3. A rimming machine for wood heels comprising a flat table having around hole in it, a circular rotary tool mounted in said hole and havingribs extending transverse to said table,

means for rotating the tool, and a guard extending part way aroundthetool.

4. A rimming machine for wood heels com prising a flat tablehaving around hole in it, a

circular rotary tool mounted in said hole and having ribs extendingtransverse to said table,

edge of a heel surface resting on the table in contact with the tool.

6. A rimming machine for wood heels having I a table with a round holein it, and a rotary tool running in the hole, said tool having aflattish annular ribbed surface substantially flush with the surface ofthe table, and a second circular ribbed surface rising from saidfiattish annular surface, to providean angle between said two surfaces,the ribs on said second-named surface running in a direction whichintersects the surface of the table.
